Which statement describes a benefit of using fission reactions? 1.)Radioactive waste must be stored for long periods of time
2.)Nuclear fuel consists of stable isotopes
3.)Gamma radiation is produced.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
